“…It is noteworthy that annually there are plenty of oriented strandboard (OSB) and plywood discarded in European and American and particle board (PB) and medium density fiberboard (MDF) abandoned in Asia [11,12]. Utilization of these materials in manufacturing of WPCs can not only reduce production costs but also remove the problem of accumulating and discarding wood industry waste.…”

The effect of individual and combined particleboard dust (PB dust) and basalt fibers (BFs) on mechanical and thermal expansion performance of the filled virgin and recycled high density polyethylene (HDPE) composites was studied. It was shown that the use of PB dust had a positive effect on improving mechanical properties and on reducing linear coefficient of thermal expansion (LCTE) values of filled composites, because the adhesive of the particle board held the wheat straw fibers into bundles, which made PB dust have a certain aspect ratio and high strength. Compared with the commonly used commercial WPC products, the flexural strength of PB dust/VHDPE, PB dust/RHDPE, and PB dust/VHDPE/RHDEPE at 40 wt% loading level increased by 79.9%, 41.5%, and 53.9%, respectively. When 40 wt% PB dust was added, the crystallization degree of the composites based on three matrixes decreased to 72.5%, 45.7%, and 64.1%, respectively. The use of PB dust can help lower the composite costs and increase its recyclability. Mechanical properties and LCTE values of composites with combined BF and PB dust fillers varied with PB dust and BF ratio at a given total filler loading level. As the BF portion of the PB dust/BF fillers increased, the LCTE values decreased markedly, which was suggested to be able to achieve a desirable dimensional stability for composites. The process provides a useful route to further recycling of agricultural wastes.

“…In recent years, approaches to the problem of sorting wood chips have been increasingly gravitating towards solutions based on machine vision (Verheyen et al 2016). Sorting becomes especially important if production involves substandard input material of low quality, as this process has a strong and positive environmental effect.…”

Given the upward trend of deforestation in the world, improving the quality of wood waste sorting operations is a major challenge in forestry from the perspective of energy saving and environmental conservation. The quality of wood chips defines their further application, whether it is production or fuel. The second case study presents a new approach to the problem of sorting wood chips for increasing their quality using machine learning and laser scanning technology. The proposed methodology includes functions to analyse the fractional size distribution among wood chips and rot detection. It shows that once a defective chip is detected, the quality control system will automatically remove it from the conveyor belt while it is moving. The minimization of wood waste will reduce logging intensity and increase the profitability of lumber enterprises.

“…Researchers and industrial partners continue to join forces in large-scale investigations to measure, model, and determine if spectroscopy has potential in a wide range of application fields, 10,11 including pharmaceutical, [12][13][14][15] food, [16][17][18][19][20] waste sorting, [21][22][23] bioprocess monitoring, 24 and metallurgy. [25][26][27][28] The potential for inline measurements is ever-increasing as new, enabling technology is being developed, e.g., enhanced silicon and InGaAs detectors, 29,30 OEM spectrometers, [31][32][33] and light-emitting diode (LED) sources.…”

Inline Spectroscopy: From Concept to Function

The field of applied spectroscopy is strongly dominated by publications presenting proof-of-concepts, lab set-ups, and demonstrations. In contrast, the corresponding number of commercial successes of inline spectroscopy is surprisingly lower. This article discusses inline spectroscopy from an instrumentation perspective. It is the authors' firm belief that the success of inline spectroscopy lies in the understanding of how the design and implementation of the optical instrumentation affects the data quality, and how this in turn will limit or enhance the performance of the prediction model. This article emphasizes the need for a strong, multidisciplinary design team, whose design process is rooted in first principles, to bridge the technology "valley of death" and convert research in applied spectroscopy into commercially successful solutions.
